INTRODUCTION============The package senskernel-1.0 provides the following opportunity for users working at Linux-based computers:  - Calculation of multi-modal surface wave dispersion and eigenfunctions     in flat isotropic elastic Earth model consisting of homogeneous layers.     Options for sphericity and attenuation corrections are included.  - Calculation of phase velocity sensitivity kernels for the same model.  - Calculation of group velocity sensitivity kernels for the same model.Package includes three programs: SURF_PERTURB, PHV_SENS_KERNEL ,GRV_SENS_KERNEL and C-shell script KERNELS.csh .CONTENTS1.

PACKAGE CONTENTS   ================The contents of the package are as follows:README         this filebin            contains of three binary 64-bit executable programs (OS RHEL 5.9)               GRV_SENS_KERNEL, PHV_SENS_KERNEL, SURF_PERTURB,               and script KERNELS.csh.src            contains of program source codesTEST1          contains of precomputed example testTEST2          directory to run your own  installation2.  INSTALLATION   ================   Use the gunzip and tar command to extract distribution contents.     ...> gunzip senskernel-1.0.tgz     ...> tar xvf senskernel-1.0.tarThis will yield a top level directory named senskernel-1.0 with an executable,along with other miscellaneous files.Go to senskernel-1.0/src directory and recompile, if necessary, all programs.To do that execute the following coomands   ...> make clean   ...> make   ...> make installThe resulting binary modules GRV_SENS_KERNEL, PHV_SENS_KERNEL andSURF_PERTURB will be installed under senskernel-1.0/bin directory. In case of problems update Makefile properly.The senskernel-1.0/bin directory originally includes binary modules compiled by gcc/gfortran v4.1.2 compiler under RHEL 5.9 (RedHat Enterprise Linux 5.9)Operational System.See an example of run in the directory TEST1 and try your own runin directory TEST2.    3. SYSTEM REQUIREMENTS   ===================   - 64-bit or 32-bit platforms   - Linux Operation System,      currently tested on RHEL 5.x, 32 and 64 bit version under      gcc/gfortran v4.1.2   - SUN OS Solaris     currently tested on Solaris rel.5.7/5.8/5.10 cc/f77 WorkShop Compilers 4.2   - Mac X      currently tested on OS 10.7 (Snow Leopard), gcc/gfortran v4.6.0   - have to work under other Linux OS and compilers with minor changes.4. TEST INSTALLATION   =================   Go to senskernel-1.0/TEST1 to see test results and after goto   senskernel-1.0/TEST2 and follow README files.
